The KievProp is designed to be installed on aircraft with engines that incorporate a gearbox or a belt drive reduction unit. This is to slow the rpm at the propeller and provide engine shock absorption.



Maximum output power on the driving shaft for 3-blades propellers is up to 145 hp.
Maximum output power on the driving shaft for 4-blades propellers is up to 180 hp.
Maximum output power on the driving shaft for 5-, 6-blades propellers is up to 200 hp.


All blades come standard with brass leading edge protection to extend the life of the blades by reducing or eliminating the abrasive effects of soil particles and the corrosive and wear effects of water. 

All Propellers are complete and include:
- Hub
- Blades
- Protractor (Pitch adjustment tool)
- Attachment Hardware

- Blade Covers

- Installation Manual/Logbook

Available options:

- Blade covers
